摘要： This is an implantable vaso-occlusive device. It is typically a vaso-occlusive coil comprising a primary helically wound coil which may then be wound into a secondary shape. Central to the invention is the use of a stretch-resisting member extending through the lumen formed, which stretch-resisting member is fixedly attached, directly or indirectly, to the coil in at least two locations. The stretch resisting member is preferably somewhat loose within the interior of the lumen so to prevent the coil from collapsing, binding, and therefore stiffening during passage of turns through the human body. The coil should bend easily. In some variations of the invention, the stretch-resisting member may be formed into coil tips at the ends of the coil using simple equipment such as soldering irons or the like. The tips are typically of the same diameter as is the coil body itself. This stretch-resisting member is for the primary purpose of preventing stretching of the coil during movement of that coil, e.g., by retrieval or repositioning after deployment. The device may have a self-forming secondary shape made from a pre-formed primary linear helically wound coil, although it need not have the secondary form. Desirably, the coil is extremely flexible and is controllaby released using a severable or mechanical joint such as an electrolytically detachable joint. External fibers may be attached to the device and affixed to the pre-formed linear member to increase thrombogenicity. The extremely flexible variation of the invention may be hydraulically delivered through the lumen of a catheter and is so flexible that it may be retrievably delivered therethrough a flow-directed catheter. The vaso-occlusive member may be also be covered with a fibrous braid. The device is typically introduced into the body through a catheter. The device is passed axially through the catheter sheath and assumes its secondary form upon exiting the catheter.

摘要： This is an artificial occlusion kit for implanting and retaining an artificial occlusion device in a body space adjacent to and extending from a body lumen in a mammal. The includes at least one occlusion device and a retaining device for blocking the migration of the occlusion device out of the occlusion site. The retaining device is radially expandable at a retaining site adjacent the body space to be occluded to a diameter that is sufficient to engage the body lumen wall at the retaining site and form a barrier across the entrance zone of the body space to be occluded. The expanded retaining device also forms a lumen for flow through body lumen at the retaining site. The retaining device may be placed in the body temporarily or permanently. At least one semi-penetrable space may also be provided in the retaining device, allowing introduction of occlusion devices into the body space to be occluded, but preventing subsequent migration of the occlusion devices out of the body space. This semi-penetrable space may also be distensible to allow for delivery of occlusion devices therethrough. An introducer wire or a tapered-tip delivery catheter may be used to distend the distensible space and deliver the occlusion devices. The retaining device structure may further include a radiopaque metal wire wound into a primary helix over an inner core member made of a superelastic alloy of nickel and titanium.

摘要： This is an implant for placement in the human body and an assembly for so placing that implant. Most desirably, it is an implant for use in the vasculature of the human body and is used to occlude some space in that vasculature as a portion of a treatment regimen. The implant itself is preferably a component of a deployment device using an electrolytically severable joint. The implant is electrically isolated from the electrolytically severable joint by a highly resistive or insulative layer. Such isolation and minimization of the conductive pathway from the placement apparatus to the body's fluids appears to enhance the susceptibility of the electrolytic joint to quick erosion and detachment of the implant from the deployment media. Although the implant itself is preferably a vaso-occlusive device, it may instead be a stent, a vena cava filter, or other implant which may be installed in this manner.
摘要翻译：这是用于放置在人体中的植入物和用于使得植入物放置的组件。最理想的是，它是用于人体脉管系统的植入物，并且用于封闭该脉管系统中的一些空间作为治疗方案的一部分。植入物本身优选是使用电解可分割接头的展开装置的部件。植入物通过高电阻或绝缘层与电解可分离的接头电隔离。从放置装置到身体的流体的导电通路的这种隔离和最小化似乎增强了电解接头对植入物从展开介质的快速侵蚀和分离的敏感性。虽然植入物本身优选为血管闭塞装置，但它可以是支架，腔静脉过滤器或可以以这种方式安装的其它植入物。

摘要： This is a catheter assembly and a section of that catheter assembly. That catheter assembly may be used in accessing a tissue target within the body, typically a target which is accessible through the vascular system. Central to the invention is the use of a braided metallic reinforcing member, typically of super-elastic alloy ribbon, situated within the catheter body in such a way to create a catheter having an exceptionally thin wall, controlled stiffness, high resistance to kinking, and complete recovery in vivo from kinking situations. The braid may have a single pitch or may vary in pitch along the axis of the catheter or catheter section. The braided ribbon reinforcing member typically is placed between a flexible outer tubing member and an inner tubing member to produce a catheter section which is very flexible but highly kink resistant. The catheter sections made according to this invention may be used alone or in conjunction with other catheter sections either made using the concepts shown herein or made in other ways. The more proximal sections of the catheter assembly are often substantially stiffer than the more distal sections due to the presence of stiff polymeric tubing or metallic tubing or composited materials in the stiffer section.
摘要翻译：这是导管组件和导管组件的一部分。该导管组件可用于进入体内的组织靶，通常是通过血管系统可接近的靶。本发明的中心是使用位于导管主体内的编织金属加强构件，通常为超弹性合金带，以形成具有特别薄壁，受控刚度，高抗扭结性的导管，以及从扭结情况完全恢复体内。编织物可以具有单个间距，或者可以沿着导管或导管部分的轴线变化。编织带加强构件通常放置在柔性外管构件和内管构件之间以产生非常柔性但高度扭结的导管部分。根据本发明制造的导管部分可以单独使用或与使用本文所示的概念或以其他方式制成的其它导管部分结合使用。由于在刚性部分中存在刚性聚合物管或金属管或合成材料，所以导管组件的近端部分通常比较远的部分更坚硬。
